This simplifies the renderer by having movement cooldowns only work one
way, and thus removes the jank from Steam rendering.
This commit also applies cooldowns for animations at decision time, as
Lynx does, which eliminates a weird special case from their spawning.
Also, Lexy mode now explicitly does not allow an actor to get cooled
twice in one tic. However, this change does make clone machines no
longer be aligned with the thing that pressed the button to clone them,
which is unfortunate.
